This base-mounted end suction pump utilizes a cast iron casing with a bronze impeller and a stainless steel shaft. A replaceable bronze shaft sleeve protects the shaft, while the dry shaft design prevents contact with the circulating fluid. The mechanical seal incorporates a ceramic seat and EPT rubber, supporting operation up to 125 PSI without a wear ring.
The motor operates at 7.5 HP, utilizes a Premium Efficiency TEFC enclosure at 1750 RPM with Aegis grounding, operates on a 380-460V / 3PH power supply, and has a DOE PEI rating of 0.47. The 'S' in the SFI series denotes Taco's advanced Self-Sensing technology, which eliminates remote sensors and field wiring by using internal mathematical algorithms to calculate system resistance and automate variable flow. The included VFD is configured with a mechanical disconnect without bypass and holds an enclosure NEMA 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
